SOLE-ROUNDING MACHINE.

To aZZ whom it may concern.

Be it known that I, THOMAS Connow, a

citizen of the United States, residing at exact description of the invention, such as i the sole during the rounding,

will enable others skilled in the art to which it appertains to make and use the same.

he invention relates to machines for rounding or for rounding and channeling the soles of shoesafter the outer sole has been temporarily secured in position preparatory to permanently sewing or otherwise securing it to the shoe.

The invention is intended primarily as an improvement in the rounding and channeling machine shown and described in Patent No. 1,030,606, June 25,1912, although it may be embodied withadvantage in other machines. In the machine of the above patent the shoe is guided during the operation through the shank of the shoe by a crease guide and is guided during the operation about the forepart by a forepart guide which is normally in raised or inactive position, and which is moved into and outof active position by the operator in passing from the shank to the forepart or from the forepart to the shank. The crease guide is so mounted that it may be moved with the fore part guide during the period that the forepart guide is inaction, and the crease guide and forepart guide are provided with 00- operating stops which are brought into engagement by the movement of the forepart guide into activeposition, and which serve position of the forepart so'n during the time that the forepart guide is in action. The forepart guide is vertically adjustable on its carrier so that it may be adjusted to vary the projection formed on and the stop which determines the position of theforedesirable to utilizethe crease guidefor guidis connected to move with the forepart guide when the forepart guide is thus adjusted, and is also independently adjustable with relation to theiforepart guide.

In doing certain classes of work it may be Specification of Letters Patent.

desirable to utilize the crease guide for guidingthe shoe about the forepart as well as through the shank, and one of the objects of the present invention is to provide means by which this result may be readily and conveniently secured.

It is also an object of the invention to provide means whereby the relative move ment between the forepart guide and crease guide as the forepart guide is thrown into operation may be determined independently of the cooperating stops above referred to, in case such independent adjustment may be found desirable for any reason.

With the above objects in View, the invention comprises the features of construction and combinations of parts hereinafter described and referred to in the claims.

The invention will be readily understood from an inspection of the accompanying drawings and the following detailed description of the mechanism illustrated therein.

In the drawings, Figure l is a sectional elevation of so much of the rounding and channeling machine shown and described in the patent above referred to as is necessary to illustrate the application of the present invention thereto; Fig. 2 is a detailed side elevation showing the forward ends of the crease guide and forepart guide and their carriers; Fig. 3 is a front elevation of the "parts shown 1n Fig. 2;

and Fig. 4 is a detailed perspective view showing the stops which are secured to the creaseguide.

The machine shown in the drawings is provided with a crease guide 2 secured to the forward end of the pivoted carrier arm 4'. and with a forepart guide 6 mounted upon the forward end of the pivoted carrier arm 8. The crease guide is held in normal position by the spring 10, and is free to move downward against the tension of the spring when the forepart guide is moved down into active position. The forepart guide carrier 8 is held normally in its raised or inactive position, and is thrown into and out of action by the operator in the manner fully described in the patent above referred to.

, carries an adjustable stop screw 18 arranged to engage a cooperating stop 20 on the crease guide when the forepart guide is brought into operation, so that the crease guide will move with the forepart. guide during the operation around the forepart of the shoe. The screw 18 may be ad usted to determine the position of the forepart guide with relation to the crease guide when the screw is in ngagement with the cooperating stop 20, and to determine the movement of the forepart guide with relation to the crease guide before the stops are brought into engagement and act to connect the guides so that they will thereafter move in unison.

The slide 1 1 may be adjusted on the carrier 8 to vary the position of the forepart guide and the stop screw 18 with-relation to the carrier 8. and thus secure the desired projection of the sole around the forepart of the shoe. The devices for securing this adjustment comprise an operating and latch lever 22 secured to the end of a rock shaft 24 which is connected to move the slide 1 1 vertically through a crank pin and slot connection, as fully described in he patent above referred to. The adjustment of the forepart guide to secure the desired projection of the sole does not affect the position of the forepart guide with relation to the crease guide during the operation of the forepart guide, since the stop 18 moves with the forepart guide when the forepart guide is adjusted.

In embodying the preferred form of the invention in a machine having the construction above described, a second and independently adjustable device is provided for determining the movement of the forepart guide carrier with relation to the crease guide and its carrier when the forepart guide is moved into operation, and for causing the guides to move in unison while operating about the forepart of a shoe. In the construction shown, this device comprises an adjustable stop screw 26 mounted on the crease guide carrier and arranged so that it may be adjusted into or out of position to be engaged by the forepart guide carrier 8 when the forepart guide is moved down into action. For convenience in manufacture the screw 26 is mounted in a projecting lug 28 formed on a clip 30 which may be secured to the crease guide or its carrier, and wh ch is also provided with a projecting lug forming the stop 20. The screw 26 may be adjusted vertically into such position that it will be engaged by the forepart guide carrier 8 before the forepart guide reaches the shoe. In such case the crease guide will continue to guide the shoe'throughout the operation, about the forepart, and will be moved and controlled by the pattern cam to give the desired form to the projecting edge of the sole. In this case the stops 18 and 20 are not brought intoengagement,

and are consequently rendered inactive.

The screw 26 may be rendered inactive by adjusting it vertically into such position that the stops 18 and 20 are brought into engagement before the carrier. 8 reaches the screw. In this case the stops 18 and20 are active, and the forepart guide engages and guides the shoe, the crease iguide noying with the forepart. guide while theyforepart guide is in action. The screw 26 may be secured in adjusted position by thelock nut 32.

While it is preferred to employ the. specific construction and arrangement of parts shown and described, and to mount the. stop screw 26 upon the crease guide, it will be understood that this construction and arrangementis not essential to the broader features of the invention, and may be varied or modified as found desirable or best suited to the construction of the machine in which 7 guide, and two independently adjustable devices for causing the creaseguide and forepart guide to move together when the forepart guide is moved into action.
